Problems solved by technology

[0005] The digital printing process of chemical fiber fabrics is mainly based on high temperature dispersion. Although the high temperature dispersion process is more mature and the effect is better, although acetate fiber is a member of the chemical fiber family, the high temperature resistance of acetate fiber is relatively weak. Traditional high temperature The dispersion process needs to be above 180°C or even 200°C to fully develop color, and the acetate fabric is at a high temperature of 180-200°C, due to its relatively weak high temperature resistance, the molecular chain will be damaged, which will cause the acetate fabric to harden. It affects the feel and quality. If the temperature is insufficient, the color effect will be poor, and it will be difficult to meet the demand for the appearance of the fabric, so there is still room for improvement.

Embodiment 1

[0088] A digital printing method for woven acetate printing, comprising the following steps:

[0089] Step 1), pre-treatment, washing the fabric, including:

[0090] Put clean water in the washing machine, add new synthetic fiber refining desizing agent and refining degreaser to the clean water, add 0.5g new synthetic fiber refining desizing agent and 0.5g refining degreaser to each liter of clean water, and then put the fabric into In the washing machine, wash in the washing machine at 90°C for 30 minutes, and take out the fabric.

[0091] Step 2), pre-type, specifically including:

[0092] The pre-treated fabric is transported to the setting machine for pre-setting. The temperature of the setting machine is 160°C, and the speed of the setting machine is 35m / min. Negative overfeeding or positive overfeeding can be adjusted as needed. In this embodiment, no overfeeding adjustment is performed. . Overfeed range is -2% to 20% of vehicle speed.

[0093] Step 3), sizing, apply...

Embodiment 2

[0107] A digital printing method of woven acetate printing, compared with embodiment 1, the difference is only:

[0108] In step 1), the fabric is put into the washing machine, washed in the washing machine at 130° C. for 20 minutes, and the fabric is taken out.

[0109] In step 2), the pre-treated fabric is transported to a setting machine for pre-setting, the temperature of the setting machine is 180°C, and the speed of the setting machine is 35 m / min.

[0110] In step 4), the dried fabric is transported into a vertical steamer, and steamed at 130° C. for 35min.

[0111] In step 5-1), the steamed cloth is transported to the cloth washing machine, the cloth washing machine is filled with clean water at room temperature, and the cloth washing machine is started for cleaning, while maintaining water injection, so that the water flow in the cloth washing machine overflows, and the water injection speed is 1L / min, overflow cleaning for 12min.

[0112] In step 5-2), stop the ove...

Abstract

The invention relates to the field of digital printing, and particularly discloses a digital printing method for tatting acetic acid printing. A digital printing method for tatting acetic acid printing at least comprises the steps of sizing and printing. The sizing step specifically comprises the following steps: applying sizing slurry on the cloth; the sizing slurry comprises the following components in parts by mass: 2-4 parts of a thickening agent; 6-8 parts of an accelerating agent; 1-2 parts of a surfactant; 60 to 70 parts of water; the accelerating agent is a compound of citric acid, sodium potassium tartrate tetrahydrate, 2, 4, 5-trichlorophenol, dibutyltin dilaurate and cardanol polyoxyethylene ether; the printing step specifically comprises the following steps: jet-printing high-temperature dispersed ink on the cloth, and then ageing at 120-130 DEG C for 35-45 minutes. The artificial leather has the effects of keeping a relatively good color development effect and relatively good hand feeling.

Description

technical field [0001] The invention relates to the field of digital printing, in particular to a digital printing method for woven acetate printing. Background technique [0002] Acetate fabric is a fabric woven from acetate fiber. Acetate fiber is a man-made fiber obtained by esterification of acetic acid and cellulose as raw materials. [0003] The acetic acid fabric has good moisture absorption, air permeability and resilience, no static electricity and hairball, and is very comfortable to wear. It is widely used in the production of various high-end clothing. [0004] With people's pursuit of beautiful appearance, solid-colored fabrics can no longer meet the demand, and various patterns need to be formed on the fabrics to meet the needs of consumers who love beauty. Among them, there are many printing methods, among which digital printing is carried out with digital technology. Printing, the effect of printing is better, and the patterns are exquisite. It is one of the...
